　　When we talk of plants, most of us will think of things that grow from the ground and have green leaves, but there are plants that do not look or act like other plants．Some of these belong to a special class of plants called fungi．

　　Fungi may appear almost everywhere．①They commonly grow in wet places where they can get food and water easily．Because fungi do not have green leaves to make their own food, fungi must take their food from animals, other plants or water．Some fungi live on dead or rotting wood, while others grow on living trees or in dirt or moss(苔藓)．Mushrooms(蘑菇)are the best-known fungi．

　　②There are many kinds of mushrooms appearing in all shapes and sizes．For example, cauliflower mushrooms are found in forests from July to October．They can grow to be as heavy as fifty pounds! They grow at the foot of trees．Squirrel's bread(松茸)is another kind of wild mushroom．Its appearance and use can explain its name．These fungi look like small golden cakes．Squirrels can easily eat them or carry them off to their hole to eat later．

　　③食品店里的蘑菇是人们精心种植的，可安全食用。People are warned never to touch or taste wild mushrooms, because some of them are deadly．Even less dangerous ones can still make a person very sick．
